Answer:

It tell us that it's necessary 2 moles of Ag in the stoichiometric proportion of the reaction.

Explanation:

The equation of a chemical reaction is a representation of the ideal reaction: 100% yield of the products and without parallel reactions. So, the equation presents the stoichiometric quantities of the substance. For example, for a generic reaction:

A + 2B → 3C

It says that it's necessary 1 mol of A and 2 moles o B to form 3 moles of C. Thus, the numbers before the substances represents the stoichiometric number of moles of that substance.

Is the process of a liquid changing into a solid when cooling a chemical reaction?
Alona [7]

Answer: The bulk of liquids separate from the standard substance through crystallization, creating a crystalline block.

Freezing is almost often an exothermic mechanism which ensures that heat is emitted when liquid transforms into concrete.

The energy emitted after freezing, known as the fusion enthalpy, is a latent heat, which is precisely the same as the energy used to melt the same volume of solid.

A particular solution of NaOH has hydronium concentration of 4x10-9 M. what is the solution’s pH?
bearhunter [10]

Answer:

The pH of the solution is 8, 40-

Explanation:

The pH indicates the acidity or basicity of a substance. PH values between 0 and less than 7 indicate acidic solutions, 7 neutral and greater than 7 to 14 basic. It is calculated as

pH = -log (H30+)

pH= -log (4x10-9M)

<em>pH=8,40</em>
